Copper alloys are used in many seawater applications due to their environmentally assisted cracking general corrosion pitting and crevice corrosion resistance as well as their anti-fouling properties. Age hardenable copper alloys such as copper-beryllium (Cu-Be) are used in subsea applications for split-lock rings and trunnions due to excellent galling resistance as it provides low coefficient of friction. Age hardening response of the alloy depends on the amount of cold work prior to heat treatment as well as heat treatment time and temperature. Precipitates and their size and distribution govern the mechanical properties of the alloy.Due to criticality of subsea designs and significant consequence of offshore failures advanced design assessment and verification analysis is required. One of the material properties used for design verification analysis is Fracture Toughness (FT); in some applications it is required that the service environment degradation effect be considered in obtaining material properties.In this work FT of a specifically prepared Cu-Be alloy was measured in air and in seawater with cathodic protection condition. The effect of loading rate on the cracking resistance of the material was determined initially and then three FT tests at the proper loading rate were performed using compact tension test specimens. It was found that loading rate does not play a significant role in FT values and environmental FT is comparable to its in-air values indicating the alloy’s resistance to hydrogen embrittlement. Scanning electron microscopy studies revealed ductile features with facets of transgranular cracking on the fracture surface.

Frequency Analysis Provides Insights During Close Interval Surveys

Product Number: 51322-18147-SG

Author: Elizabeth Nicholson

Publication Date: 2022

$20.00

Close Interval Surveys (CIS) are frequently performed on pipelines to measure the pipe to soil potential. While the instrument is connected to the pipe it is possible to obtain additional types of readings that can be analyzed to provide further information. Many modern electronic instruments are capable of functioning as oscilloscopes in addition to obtaining synchronized CIS readings. The information captured by the oscilloscope function provides a waveform for further analysis. The waveform is captured as a raw, unfiltered signal with at least 2000 data points per second for the duration of the interruption cycle or longer.

From 6Mo To Ni-Base – Characterizing The Corrosion Performance Of Two Important Material Groups

Product Number: 51322-17935-SG

Author: Björn Helmersson

Publication Date: 2022

$20.00

Stainless steels and Ni-base alloys are often considered as construction materials in applications where highly corrosive conditions are expected. High levels of halides, low pH and high temperatures are factors that often contribute to the selection of such materials.

Ten different alloys have been included in this work, representing a range of highly alloyed stainless steels and Ni-base alloys. The purpose has been to evaluate the corrosion resistance of stainless steels with alloying content in the 6Mo range or higher, and competing Ni-base materials. The austenitic grade N08904 and two super-duplex grades have also been included for reference.

Sacrificial or Galvanic Anodes Cathodic Protection System is an excellent anticorrosion solution which offers to immerse structures a long-term protection. In TotalEnergies and in the Oil & Gas Industry in general, such system provides confidence, efficiency together with little maintenance over years which is a very good point for the subsea integrity of jackets (or pipelines) when knowing all other operational constraints or corrosion issues that can be met at the surface level.

Thus, from TotalEnergies experience, it has been established that as long as:1/ the CP system is correctly designed (taking into account the applied - or not - painting on the jacket) following the recognized international codes and standards (DNV RP-B-401, ISO 15589-2.

Corrosion Under Insulation (CUI) is a major challenge for different process industries. Today it is managed in many ways ranging from a full removal of insulation to a minimal maintenance including some inspection methods with insufficient non-destructive testing. These extremes exhibit a lack of understanding and a lack of systematic approach in managing the CUI risk globally.A joint industry project on CUI has developed a methodology that would help identify assess and mitigate the CUI risk in a systematic manner. Living in the age of digital transformation the resulting recommended practice is being digitalized into a web application that will offer its users an industry-recognized best practice in managing the CUI risk of their assets. The end-users will have the possibility to share their knowledge and learn from other users’ experiences through an established Globally Shared Database (GSD). Such synergy across the industries will enable a continuous methodology improvement and future development of the machine learning within the Application. Furthermore a separately developed feature will use digital twins of the users’ assets linked with assets’ integrity data and other relevant data providing more efficient communication and work processes. The ultimate goal of the Application is to ensure safe and reliable operations and thus improve the safety of life property and environment.Keywords: corrosion under insulation risk joint industry project web application globally shared database digital twin machine learning

Carbon and low alloy steels (CS and LAS, respectively) used for exploration and production in the oil and gas (O&G) industry are normally exposed to environments that may contain H₂S in a wide range of concentrations. In aqueous solutions, H₂S acts as a cathodic poison.^1,2 A cathodic poison inhibits the recombination of atomic hydrogen to H₂, and as a result, favors its absorption by the metal.^1,2 In the presence of a susceptible microstructure and the simultaneous effect of applied or residual tensile stress, a crack can nucleate and propagate, when a critical concentration of hydrogen is reached in the metal.³ This environmentally assisted cracking (EAC) phenomenon is known as Sulfide Stress Cracking (SSC).² SSC is commonly addressed as a case of hydrogen embrittlement (HE) damage.²

Full ring ovalization test is performed in line pipe to assess the susceptibility to sulfide stress cracking when the material is subjected to load and sour service conditions. A full ring test was performed under BS 8701 standard1 for a 36 inches welded line pipe, X65 material. The region of interest was monitored with strain gauges to control loading at the required stress level. After test completion, the NDT and visual inspection reported indications in some areas out of the region of interest. A detailed analysis was performed to find out the sources of indications. The study included material analysis and revision of sample preparation and test setup variables. For test preparation and setup analysis, 2D and 3D finite element work was performed to understand the effect of those variables on the cracking occurrence. The finite element analysis (FEA) results showed that geometry variations, loading control and testing setup have a considerable influence on the applied stresses. It was found that some zones out of the region of interest can be over stressed due to slight modifications in loading conditions. As a part of the analysis, a new test was performed with the corresponding adjustments observed in the numerical model, and strain gauges were located at the points where the FEA showed higher stress zones. The strain gauge readings confirmed the stress fields observed with FEA. Additionally, the second tested sample successfully passed the test.
